Research Summary:

Dr. Hynynen's research has focused on studying the effects of ultrasound beams on tissue and their utilization in therapy. He is investigating the use of focused ultrasound for noninvasive surgery, vascular surgery, targeted drug delivery and gene therapy. He has developed theoretical models to help understand treatment parameters and to allow optimization of treatment devices. He has conducted in vivo experiments to investigate the various biological end points that can be induced by controlling the sonication parameters.

His research on ultrasound transducers has been used to design and develop new phased array applicators and better ways to deliver therapy. He is also looking at the use of magnetic resonance imaging to detect and quantify noninvasive ultrasound exposure in vivo. He has developed several systems that are being tested clinically. Dr. Hynynen is currently exploring new ways to utilize ultrasound for imaging with the aim of using the methods for controlling delivery of therapy and aid in tumour diagnosis.
